PHONOGRAFH-HORN.

Specification of Letters Patent.

Application filed. March 31, 1908. Serial No. 424,328.

To (112 whom it may concern:

Be it known that I, PETER \VEBER, a citizen of the United States, and a resident of Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in. Phonograph-Horns, oi which the tolldwing is a description.

My invention relates to phonograph horns of the type in which the flaring bell is made in a single piece which is separately united to the small end or body portion of the horn, and. has been preferably embodied in a horn, the axis of which is curved so that the horn extends upward from the phonograph sound box and the mouth of the bell occupies substantially a vertical plane facing in the some direction as the phonograph, as described and claimed in my application filed October l l, 190?,N0. 397,283.

The present invention also relates to inrproved means for flexibly uniting a horn of this character with the sound box of the phonograph.

In order that the invention inay be more fully understood, reference is hereby made to the accompanying drawing of which-,

Figure 1 is a side elevation of a horn. constructed in accordance with my invention and applied to a phonograph which is illus trated in dotted lines; Fig. 2 is a section on line 2-52 of Fig. 1; Fig. 3 is a detail plan view of the means for locking the bell to the body of the horn; Fig. & is a sectioh on line d-4 of Fig. 3; Figs. 5 and ('3 are views similar to 3 and i of a modified locking device; Figs. 7 and 8 are similar views of zinother modification; and Fig. ,9 is ,a; view similar to the lower portion ofFig. 1 showing a phonograph in which the nipple of the sound box extends vertically and. showing a modified construction of coupling for connecting the lower end of the horn with the said nipple.

The horn shown comprises a hell 1 of metal, wood or other suitable material, the smell end of which is provided with a pair of apertures 2 and an outwardly extending pin 3. 4- is a curved section or body, the small end of which is adapted to be con nectcd to the sound box of the hono 'ra h a. The large end of the section 4 is pro vidcd with a metallic ring 5 of tapered form which has a pair of inwardly project; ing pins 6 adapted to be inserted within the openings 2, and said ring is formed with a notch 7 adapted to receive pin 3. There is a locking latch 8 pivoted at 9 to the ring 5, the same being formed with a. handle 10 and a cam surface 11, which, tends to draw the bell 1 into the ring 5 with a wedging action, due to the tapered form of these parts. s

In the device of Figs. 5 and 6 there is a locking latch 8' pivoted at 9 to the lugs 12 which are rigid with the ring The forward end of said latch 8 is provided with a handle 10 and the latch has an opening 11 which is adapted to receive the pin 3, and there is the same wedging action of the hell 1 with respect to the ring 5 as the parts are drawn together-by the latch 8 being forced down upon the pin 3 into the position shown in Fig.

In the device of Figs. 7 and 8, the latch 8 wl'iich is pivoted st ll to the lugs 12 carried by the ring 5, is formed with. a handle 10 and a cross-rod 11 which cocperatcs with ayoke or Y-shuped member 13 @cured to the bell 1,. to wedge the bell within the ring 5, the surface of the yoke 13 having a cam action with respect to the cross rod 11 The small end of the section 4-. may be united to the nipple b of the sound. box by any suitable flexible connection, but I prefer to use a hollow or tubular ball and socket oint or coupling H. In the structure shown in Fig. i, this coupling fits tightly upon the nipple 0 and slides freely within the lower end of the s :tion

in the sir og'ruph carriage a is of slightly (lifter nt form, and the nipple Z) of the sound hoe: extends vertically. With a phonograph of this type, one n'icmber of the ball and socket coupling H: may heiintegral with the section t as shown, and the other member fits loosely upon the said nipple 7/. in both forms the weightof the horn is carried by a line-. port r: trout which the horn is suspended. and the sliding; connection between the horn and coupling in Fig.1 and between the coupling and nipple in Fig. 9, permits the pro gross-ire movement or feed of the phonograph Yu'riage without affecting the con nection of the sound i303; with the horn.

Having now described my invention. what i claim is:

LA. phonograph horn comprising separable sections a least one of which has a tapered engaging surl'ace, and means for ueture shown in Fig. 9 the phom;

uniting the same comprising one or more pins carried by the end of one section and adapted to be inserted in openings formed in'the other section, a pivotal latch carried in, one section and adapted to engage a projection carried by the other section, said latch and projection being so formed that their engagement draws the sections together with a wedging action. substantially as set forth.

2. A pl'ionograph horn coniprisin" a pair of separable sections at least one or which has a tapered engaging surface, and locking means there or comprising a latch pivoted to one of sa sections, and a pin rigid with the ther section, said latch being formed with a cam surface for engaging said pin' and drawing said sections together with a wedging action, substantially as set forth.

3. A phonograph horn comprising a pair of separable sections, a stiffening ring ap plied to the end of one of said sections, a projection rigid with the other section, and a latch pivoted to said ring and adapted to engage said projection for drawing said section and ring together, said latch and pro- .in the jection heing soxformed as to exert a wedge like or cam action on each other during the pins and with a projection rigid therewith adapted to be received by said notch, and a latch pivoted to said ring and adapted to engage said projection for drawing said pin into said notch and thereby drawing said section and ring together, said latch and grojection'bcing so formed as to exert a wedge-like or cain action on each other durg pivotal movement of the. latch, sub stantially as set forth.
